hello,
i have a configuration with 2 cas servers and 2 mailbox servers. yesterday i added 3rd cas server. I took about an hour to configure virtual directries and certificate. during that time some outlook clients switched connection to the new cas, and of course
couldn't, so they lost connectivity to exchnage.
some other clients kept their settings but also lost connection to exchnage. For some of them, restart was enough to connect again, but for some i had to create new outlook profile to connect them again to excanage.
both outlook 2010 and outloo 2013 were affected.
Does anyone have idea why? I don't know if i did something wrong or is this expected?
